Current Journal ReviewsThree Centuries of Climate Change on Canada's Highest Mountain: Snow accumulation data from an important new study add to the ever-growing body of evidence that demonstrates that the "hockey stick" temperature history of the Northern Hemisphere, which is so highly-hyped by climate alarmists, is not a valid representation of the real world.

Effects of Elevated Atmospheric CO2 on Soil Microbial Organisms: Increases in atmospheric CO2 concentration often lead to greater plant growth, both above- and below-ground. The below-ground part of this observation suggests there might possibly be a concomitant increase in the number of soil microorganisms associated with the bigger plants. This paper tests this hypothesis.
